QUESTIONS & ANSWERSAsk a Question
would you also be able to get mechanical dampers on the inlet side for this fan
We do not have additional dampers available for this unit.
However; it does come with a butterfly damper that opens when the fan is running, and closes water/air tight while the fan is not in use.
